This invention relates to new and useful improvements in means for attaching lintels to concrete spandrels.

It is the principal object of my invention to provide simple and efiicient means whereby the threaded ends of the anchor bolts embedded in concrete spandrels or beams may be easily turned for registry with the holes which receive them in the supports that they secure to the face of the concrete structure. Anchor bolts which are not free to be easily bent after they are embedded in the concrete, are difiicult to aline with the bolt holes in lintels or other supports, with the result that this operation is only effected with much labor, and not infrequently, with injury to the structure.

Other important and incidental objects will be brought out in the following specification and particularly set forth in the subjoined claims.

In the accompanying drawings illustrating my invention, Figure 1 is a perspective view of a brick veneer-concrete spandrel structure 5 with the form and spacing washer removed. Figure 2 is a perspective view of the anchor bolt, spacing washer and nut. Figure 3 is a longitudinal sectional View taken through the concrete form and spandrel, showing the anchor, anchor bolt and spacing washer embedded in the concrete before the form and washer are removed. Figure 4 is a similar View taken through the concrete after the form and washer are removed, and showing in dotted lines how far the threaded end of a bolt may be bent to easily enter its respective bolt hole in the lintel.

Referring to the accompanying drawings illustrating my invention, the numeral 1 4.0 designates a spandrel or beam of concrete or other monolithic material. In the present instance this spandrel is constructed in a wood form 2 above the head 3 of a window frame.

Embedded in the concrete 1 are conventional anchors 4 secured to eye bolts 5, one of each being shown in Figure 3. In this figure the eye bolt projects outwardly through a hole in the form 2 to receive on its threaded end, beyond the form, a nut 6.

Serial No. 369,547.

PATENT OFFICE T For the purpose of leaving a space in the concrete around the bolt 5 between its eye end and that portion of it which will pro- ]ect beyond the face of the concrete, after .the latter is poured, there is mounted on their.-

crete a frusto-conical hole 8 within the limits of which the threaded end of the bolt is:

free to be bent to easily enter a respective bolt hole in a lintel or angle 9. The nut 6 is then applied to the bolt to draw the angle 9 tightly against the face of the concrete, to support the brick veneer 10 above the jamb 11 of the window frame.

If the space 8 were not left around the threaded ends of the anchor bolts, it would be necessary to drill the bolt holes in the angle 9 after the bolts were embedded in the concrete; otherwise the angle could not be easily or properly secured to it.

I do not desire to be limited in the use of my invention to the edifice shown and described, since it may with equal facilityw be used. for the attachment of a lintel or other support to a ceiling, floor or other monolithic structure.

Having described my invention, I claim:

1. Means for attaching a support to a monolithic member, comprising anchors for embedment in said member, fastening elements to whose inner ends the anchors are secured, said support formed with holes to receive said fastening elements, and a spacing sleeve on each fastening element for embedment in the monolithic member near its face portion for the purpose specified.

2. Means for attaching a support to a monolithic member, comprising angle anchors for embedment in said member, eye bolts to whose eye ends said anchors are secured, said support formed with bolt holes toreceive the threaded ends of the bolts, nuts on said bolt ends to draw the support against the embedment in said spandrel, eye bolts to whose eye ends said anchors are secured, said lintel formed with bolt holes to receive the threaded ends of the bolts, nuts on said bolt ends to draw the lintel against the spandrel, and a frusto-conical washer on each bolt for embednnent in the spandrel near its face portion for the purpose specified.

In testimony whereof I have hereunto set my hand this 7th day of June, 1929.

ARTHUR C1 HEITMANN.
